Dear Carolyn, ENTS,
I can't recall where I got this from but there were apparently two
standard mast sizes in New England in colonial times. They were hewed
square in the woods for ease of handling and to remove the sapwood and
bark.
The 100 footer was hewed to 36" x 36" at the butt and tapered to a 24"
x 24" at the tip
The 125 footer was hewed to 48" x 48" at the butt and tapered to a 30"
x 30" at the tip
This larger one required a absolutely straight pine of about six
foot DBH that was still three and a half feet in diameter 125 feet
up! The 100 footer required a pine over 4' diameter above the butt
swell and about 3' diameter 100 feet up. Hundreds of such trees were
cut in New England attesting to the presence of some magnificent
trees. I doubt there is a pine standing today of sufficient size,
soundness, and straightness enough to make the smaller one.

BTW, does anyone know how tall Her Majesty's ship masts needed to be?
Isn't
that what most of the biggest and best were used for?

>> A few more thoughts/responses about white pine growth/measurement:
>>
>> As for the capability of people 200 years ago to measure the

>> ³did they?² Often the reports of these very tall trees came from

>> style I have seen them, i.e. ³early lumberman reported thatŠ.² etc.
>>
>> One thing I have seen in reports from early lumbermen of the trees
>> they cut down, is a focus on data such as, ³at a height of 120 feet
>> the tree had a top diameter of 20 inches,² or some such thing. They
>> report this way because they are interested in how many logs the tree
>> has produced.
>>
>> So here is what MAY have led to some of these reports. If a
>> gigantic white pine is 200 feet tall, and at a height of 160 feet
>> still has a diameter of something like 20², someone could read that
>> report and say, ³Oh at 160 feet the tree was still 2² in diameter, so
>> then it must have been 250 feet tall. Yes, many younger white pines
>> have a rather gradual taper. A tree 20² in diameter in a young forest
>> can be 100¹ tall. But with very old trees, the taper at the top can
>> be very, very rapid. A very old white pine could have a diameter of
>> 20² near the top, and be only 40 feet taller, or perhaps much less.

>> length. A dominant crown will be somewhat longer‹extend further down‹
>> than a co-dominant tree.
>>
>> The next crown class is the intermediate. Here the tree is closely

>> its competitors. The crown is narrow, and depending on the species
>> and the kinds of trees it is competing with, it can be either rather
>> short, or rather thin foliaged.
>>
>> White pines are classed as a moderately intolerant tree, meaning that

>> that to grow well in height, a white pine needs to be in either a
>> dominant or a strong co-dominant crown position. To grow well in
>> diameter, it should be in a dominant crown position.
>>
>> Norway spruce is more tolerant than white pine, and therefore can
>> grow better in an intermediate or marginal co-dominant crown position
>> than white pine. White pines that are in an intermediate crown
>> position, or perhaps also in a marginal co-dominant crown position,
>> usually will lose vigor and be overtopped.
>>
>> Well, sorry, I see I am giving too much background here. The basic

>>
>> Finally, occasionally a white pine tree growing far above the
>> surrounding trees did not in fact grow as an emergent tree, but grew
>> in a forest with other trees in a dominant or co-dominant crown
>> position, and then, either because the surrounding trees were removed,
>> or died for some reason, this tree will stand in a very, very strong
>> emergent position. That does not mean that it grew to its present
>> height as an emergent.
